I have been divorced from my verbally abusive husband for about 2 years now. Immediately (4 days) after I left he started seeing a girl 10 years younger than us. They have broken up and reunited too many times to count. Now she wants to be "a part of" my daughters' lives. She has never met them because their relationship was "not serious". Now she is insisting that she be a part of my ex's family and he part of hers which includes my daughters. My daughters are only 5 years old and love everyone that talks to them. I am torn apart by this and am having so much difficulty dealing with this that I can't sleep and at night and I obsess about it all day long. I don't know why it bothers me as badly as it does. I wonder if anyone has had similar feelings in the same situation or if anyone can offer some advise. Please.
